An organizer says about 30 people showed up at a Tennessee motel to give cheek-swab DNA samples as people adopted through a nearby Georgia clinic hope to identify biological relatives before time for reconnecting runs out.

More than 200 infants in the 1950s and ’60s were relocated in off-the-books adoptions at the late Dr. Thomas Hicks’ clinic in McCaysville. DNA testing may be their only way to confirm biological links because they have no records of their natural parents.

Several adoptees attended the free DNA sampling opportunity Saturday in nearby Ducktown, Tennessee. Organizer Melinda Elkins Dawson estimates about 70 percent of those who showed up to give samples could be potential relatives of adoptees.

Dawson was one of the newborns relocated from the clinic. She now lives outside Canton, Ohio.
